I have a 1994 F250 5.8 4wd E4od. I've been experiencing hard shifts, speedo non operational. Tranny shop says I'ts reading a VSS failure. I've been told there are two VSS, one on the rear end that primarily controls the Antilock brake function. And the other is at the tranny somewhere. At the parts house two are listed and I bought the one that is listed to be located on the tranny, but for the life of me I can't find it on the tranny. Can anyone help???

 

your VSS is in the rear axle.its up on top in the center.you can't miss it.
that will send the E40D for a loop lol.so don't drive the truck until you replace it.
very easy to do.
it's not in your trans nor your transfer case.
that was changed in '92+

 

See, this is what is confusing me. Because there are two vss listed for this truck at both Napa and Car Quest and even other online parts suppliers. And two sources have told me that the one on the rear end is primarily for anti lock brake function, which became standard equip in 92-93. So where is the other one located.

 

You only have the one that is on top of the rear end. Both Napa and Car Quest and even other online parts suppliers are wrong for your truck.

However the 1994 F53 with a E4OD does have it on the transmission extension housing and not the rear end.
The reason I said this is because the one for the transmission extension housing looks the same but will not work in the rear end as it sets at a slightly different depth. So do not get the wrong one.
The one that most of the books say fits yours was not used from 1992 to at least 1996 on the F-series trucks.

The one for your truck:

+1 on that, the parts store listings are misleading at best for these trucks.. lots of errors and incomplete information. The guys here know these trucks better than anyone so you can trust the information they give you.

 

And that goes double for anything Bill or Paul tell you.

 

Hi All, I have the same issue with my 94 F150 5.0 4x4. I did put in a new vss, and it that still didn't work. Am I missing something? Thanks, Mike

 

speedo not working or just a trans problem?

 

both,the speedo is inop and the trans is shifting very hard. Also ABS light is still on. I replaced the sensor on top of the rear diff.

 

mine was doing the same thing except my speedo was working i disconnected tne abs controller behind the grove box now i can drive my truck but the back brakes will lock up opps never had abs in all the older trucks ive had

 

what about the trans shifting hard,I have been told it is the VSS. I replaced the one on the rear diff and still is shifting hard. There is no VSS on the trans

 

Check the wire to the vss, could be broken

 

checked all wires,nothing broken. Is that considered the VSS that is located on the top of the rear diff ? for this year. I heard that the VSS is causing the problems I am having (ABS light on,hard shifting and no speedo)

 

Unplug the RABS module and see if that fixes it.

 

is that the one behind the glove compartment ?
